SkyVision combines the communication industry’s most advanced technologies with the in-depth knowledge of experienced professionals. This allows us to provide customers with highly optimized satellite and fiber networks that guarantee both cost-effectiveness and the most reliable connectivity.
Some of the technologies SkyVision employs include:
Very Small Aperture Terminal (VSAT) is a small earth station used for broadcast, reception and interactive communications via geosynchronous satellites. Typical VSAT antenna diameter sizes are between 1.8 to 2.4 meters and utilize Ku-Band and C-Band for satellite transmission.
SkyVision services employing VSAT include:

Digital Video Broadcasting is a suite of internationally accepted open standards for digital television. Digital Video Broadcast – Satellite (DVB-S) defines the encoding format for multiple video channels on a single QPSK satellite carrier. DVB-S2 is a next-generation advanced version of DVB-S that offers more capacity and stronger forward error correction at low signal levels.
SkyVision services employing DVB include:
Single channel per carrier (SCPC) refers to using a single signal at a given frequency and bandwidth. Most often, this is used on broadcast satellites to indicate that radio stations are not multiplexed as subcarriers onto a single video carrier, but instead independently share a transponder. It may also be used on other communications satellites, or occasionally on non-satellite transmissions.
SkyVision services employing SCPC include:
- SkyVision DVB/SCPC
- SkyVision DVB/SCPC over Inclined Orbit
- SkyVision Combi
- SkyVision Satellite Cellular Backhaul Service
A geostationary satellite is a satellite revolving approximately 22,000 (36,000 km) miles above the earth’s surface in the plane of the equator, with an orbital period equal to one sidereal day. Satellites positioned in a GEO orbit appear to an observer on the surface of the earth as stationary objects in the sky. All SkyVision services employ geostationary satellites.
Inclined Orbit Satellites
A satellite in an inclined orbit is the same as a satellite in a geostationary orbit, with one important difference: Once a satellite has been placed into a geostationary orbit it gradually starts to drift into a figure-eight orbit, due to the gravitational influence of the sun and moon. Keeping a satellite in its geostationary orbit (in order to maintain contact with a fixed antenna) requires activating thrusters powered by large supplies of rocket fuel, activated in bursts every few weeks. Inclined-orbit technology employs a motorized antenna technology to track (i.e. maintain contact with) the satellite’s natural figure-eight orbit. Allowing the satellite to oscillate with the natural gravitational pull dramatically saves on fuel, thus both extending the satellite lifespan and reducing its operational costs.
Multiprotocol Label Switching integrates Layer 2 information about network links (bandwidth, latency, utilization) into Layer 3 (IP) within a particular autonomous system – or ISP – in order to simplify and improve IP-packet exchange. MPLS gives network operators a great deal of flexibility to divert and route traffic around link failures, congestion, and bottlenecks.
